IMPROVEMENT IN VENTILATQRS OR BLOWERS.

' The Schedule referred to in these Letters Patent: and making parte! the s'am.

I, JOHN F. COLLINS, of the city of New York, county'of New Yori: and State ot' New York, have invented certain Improvements in .Ventilators eor Blowers, of which the lollowing is a specification. A'

This invention relates to al novel device for withdrawing the air from orfor forcing the Lsame into buildingsfo r a blast for furnaces, for blacksmiths, forges, or for-withdrawing the vaporsfrom sugar, molasses, glue, dyes, dye-woods, duc., while being boiled under a partial vacuum, for the purpose of reli'ning or crystalizing, for withdrawing vapors lighter than water, or having a lower boiling point, as alcohol, &c.,- and for other similar purposes.

In the accompanying drawing- Figure I represents an end view.

Figure 2, ya side .vieux Figure 3, a sectional view of the base-piece below the iiange D.

4Figure 4, a'top view of fig. 3 at flange D.

Figure 5, a view ofthe device standing perpendicular, as placed when used to produce a-pa1tial vacuum.

Ih'e device consists of a hollow shaft or tube, A, connecting with the base-piece 'B by the ange D and the conduit at the coupling-joint Il, and having upon it a fixed pulley, J. r

O O G O are hollow trumpet or semicircular funnelshapedarms, connecting with B- at. the points 'O O. These may be increased or diminished in number, as desired. .l

The base-piece -I3 contains four compartments, two of which are shown iu. fig. 3, K K, a plan view at flange D being shown in lig. 4. 'Iliese compartments may'also be increased or diminished as desired.

E E are standards to" support the device, terminating in bearings at'l41 F.

L, Iig. 1, is a strap securely bindingthe arms O O C C together for additional strength.

His a packing-joint, the shaft A being movable to that point, while the conduit beyond is stationary.

Ihe operation of my invention is very simple and as follows Power being applied by va belt on the pulley J, which, as before stated, is fastened to the hollow shaft A, the whole is 'rapidly revolved, taking up the air through the hollow arms O C C O, and forcing it into' the compartments of the base-piece B; thence out through the hollow sliaflt A, and, by'nieans of the eonduit,`beyond the packing-joint H, conveying it to where the air current is desired. r

In usingit for the withdrawal of vapors in refining, concentrating, or crystalizing, it is to be inverted or (placed perpendicular-within the vacuum-pan or other" `vessel used, as shown in fig. 5. Y

\ I have also found that this device is specially adapted to raising water where large quantities'are required at a moderate elevation, and that it also answers admirably as an ordinary well-pump when placed at the. bottom of a 4well,the hollow shaft A being lengthened as required.

Itis also adapted to theventilation of railway and street-cars whensuspended inside from the root', and attached to any. form of windmillabove the roof to be propelled bythe motion of the car. l'

There are several other purposes for which the device may be used witlLproiit, but the foregoing are the principal ones to which I have applied it.

Having described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The base-piece B,divided into compartments K, one for each arm, 'so that the current of one'arm cannot counteract that of the others, substantially as set orth.

2. The combination ofthe hollow arms O'O CO, the base-piece B, divided into compartments K, the hollow driving-shaft A, and the packing-joint H, combined, constructed, and operating together. substau` ti'ally as described, and foi the purposes set forth.
